# Wasm

查询链上 wasm 模块的示例代码片段。

## 使用 gRPC

### 获取合约账户余额。注意可以传递分页参数以获取更多账户。

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { ChainGrpcWasmApi, PaginationOption } from '@injectivelabs/sdk-ts/client/chain'

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc)

const contractAddress = 'inj...'
const pagination = {...} as PaginationOption

const contractAccountsBalance = await chainGrpcWasmApi.fetchContractAccountsBalance({
    contractAddress,
    pagination /* 可选分页选项 */
})

console.log(contractAccountsBalance)
```

### 获取合约相关信息

```ts theme={null}
import { ChainGrpcWasmApi } from "@injectivelabs/sdk-ts/client/chain";
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc);

const contractAddress = "inj...";

const contractInfo = await chainGrpcWasmApi.fetchContractInfo(contractAddress);

console.log(contractInfo);
```

### 获取合约历史

```ts theme={null}
import { ChainGrpcWasmApi } from "@injectivelabs/sdk-ts/client/chain";
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc);

const contractAddress = "inj...";

const contractHistory = await chainGrpcWasmApi.fetchContractHistory(
  contractAddress
);

console.log(contractHistory);
```

### 获取智能合约状态

```ts theme={null}
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";
import { ChainGrpcWasmApi, toBase64 } from "@injectivelabs/sdk-ts/client/chain";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc);

const contractAddress = "inj...";
const query = "...";
const queryFromObject = toBase64({ get_coin: {} });

const contractState = await chainGrpcWasmApi.fetchSmartContractState({
  contractAddress,
  query /* 可选字符串查询 - 必须是 base64 格式或使用 queryFromObject */,
});

console.log(contractState);
```

### 获取智能合约原始状态

```ts theme={null}
import { ChainGrpcWasmApi } from "@injectivelabs/sdk-ts/client/chain";
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc);

const contractAddress = "inj...";
const query = "...";
const queryFromObject = toBase64({ get_coin: {} });

const rawContractState = await chainGrpcWasmApi.fetchRawContractState({
  contractAddress,
  query /* 可选字符串查询 - 必须是 base64 格式或使用 queryFromObject */,
});

console.log(rawContractState);
```

### 获取与合约关联的代码

```ts theme={null}
import { PaginationOption } from '@injectivelabs/sdk-ts/types'
import { ChainGrpcWasmApi } from '@injectivelabs/sdk-ts/client/chain'
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc)

const pagination = {...} as PaginationOption


const rawContractState = await chainGrpcWasmApi.fetchRawContractState(
pagination /* 可选分页选项 */
)

console.log(rawContractState)
```

### 获取与合约代码关联的信息

```ts theme={null}
import { ChainGrpcWasmApi } from "@injectivelabs/sdk-ts/client/chain";
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";

const endpoints = getNetworkEndpoints(Network.Testnet);
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc);

const codeId = 1;

const codeDetails = await chainGrpcWasmApi.fetchContractCode(codeId);

console.log(codeDetails);
```

### 获取与代码关联的合约

```ts theme={null}
import { PaginationOption } from '@injectivelabs/sdk-ts/types'
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { ChainGrpcWasmApi } from '@injectivelabs/sdk-ts/client/chain'

const endpoints = getNetworkEndpoints(Network.Testnet)
const chainGrpcWasmApi = new ChainGrpcWasmApi(endpoints.grpc)

const codeId = 1
const pagination = {...} as PaginationOption

const contracts = await chainGrpcWasmApi.fetchContractCodeContracts({
  codeId,
  pagination /* 可选分页选项 */
})

console.log(contracts)
```
